Plots by subject
Hello! I need some help with creating plots for each study subject. I have
tried the 'for' command as described in 'An Introduction to R', but I wasn't
successful.
Here's what I want to do:
-Create and save the following overlayed scatterplots for each subject (1 to
n).
-The data frame is in the form of one line per visit per subject (so more than

LIMMA contrast.matrix
Dear R-Help,
I am using the LIMMA User's Guide 5 January 2007 PDF version. For the
example show in Section 7.4 DIRECT TWO-COLOR DESIGNS (pgs. 33-34), I
could not grasp the rationale in developing the contrast.matrix with
these R statements (">" indicates the R command prompt):

PREDICTIONS from a PIECEWISE LINEAR (mixed) MODEL: THEY AIN'T LINEAR BETWEEN BREAK POINTS!!
I Dears,
if that wouldn't take u too much effort I'd like to ask for a swift opinion:
I have a alinear (mixed effect) model that I wish to run as a piecewise one.
When I predict the values Iget quite some odds and disturbing results:
The predicted stright line after the break point is not straight at all,
instead behaves like if it was a hig order polynomial or something
similar!!!!

[PATCH v2 02/15] mm/mmu_notifier: add an interval tree notifier
From: Jason Gunthorpe <jgg at mellanox.com>
Of the 13 users of mmu_notifiers, 8 of them use only
invalidate_range_start/end() and immediately intersect the
mmu_notifier_range with some kind of internal list of VAs. 4 use an
interval tree (i915_gem, radeon_mn, umem_odp, hfi1). 4 use a linked list
of some kind (scif_dma, vhost, gntdev, hmm)
And the remaining 5 either don't use

Alas :( I feel there must be a bug in here still, but onwards!
One of the main sad points was it didn't make sense to use the
existing seqlock/seqcount primitives as they have

glmmBUGS fails to accept higher level covariates

I am using glmmBUGS to fit a multilevel model. Treatments are nested in

The predictors are:

at the Course level: Weight in KG and Age
at the Patient level: Weight in KG and Age
I am trying to fit a multilevel model as in lmer, but in BUGS. Here is an

v1.1 alpha1: can't pop/imap login with LDAP
Hi,
We recentlty upgraded our dovecot from v1.0.2 to v1.1ahpha1 under CentOS 4.4.
Also, we are using Postfix 2.4.3 and OpenLDAP 2.3.35.
We've been using LDAP for our POP/IAMP user authentication, however after
upgrading to v1.1alpha1, LDAP authentication does't seem to be working
properly.
We re-examined the source code, and made a few modification.
We are suspecting that...

anova.coxph for multiple events model
Hi,
I'm trying to do a multiple events model using coxph. I need to choose which
covariates stay in the final model and i'm using anova but it seems that it
doesn't work with robust variances as a error message appears when I try to
do it:

About the covariant
Hi all,I have some questions about the covariants of regression.
My target: To explore the trend of CD4 level through a period of time.
Response variable: CD4 count
Explanatory variable:time
Also, the demology information is available,such as gender,occupation,income
level...
Q1,Are these variables of demology information called covariant?
Q2,How can I correct the impact of

Indexing from two variables
Hello, thank you all for your patience and time
I am essentially trying to get disorganised data into long form for linear modelling.
I have 2 dataframes "rec" and "book"
Each row in "book" needs to be pasted onto the end of several of the rows of "rec" according to two variables in the row:" MRN" and "COURSE" which match.
